SD-0625 Asphalt Brookfield Rotational Viscometer

  ◆◆Purpose 

     This instrument is manufactured according to the JTJ052-2000 and SH/T-0739-2003 asphalt Brookfield rotational viscosity test standards. It measures the apparent viscosity of road asphalt within a temperature range above 45°C using the rotational method, expressed in millipascal-seconds (mPa·s). Based on the measurement results, the recommended mixing and compaction construction temperature ranges can be determined.
